Abstract
Dendritic cell-based (DC-based) vaccines are promising immunotherapies for cancer. However, several factors, such as the lack of efficient targeted delivery and the sources and types of DCs, have limited the efficacy of DCs and their clinical potential. We propose an alternative nanotechnology-based vaccine platform with antibacterial prophylactic abilities that uses gold glyconanoparticles coupled to listeriolysin O 91-99 peptide (GNP-LLO91-99), which acts as a novel adjuvant for cancer therapy. GNP-LLO91-99, when used to vaccinate mice, exhibited dual antitumour activities, namely, the inhibition of tumour migration and growth and adjuvant activity for recruiting and activating DCs, including those from melanoma patients. GNP-LLO91-99 nanoparticles caused tumour apoptosis and induced antigen- and melanoma-specific cytotoxic Th1 responses (P ≤ 0.5). We propose this adjuvant nanotherapy for preventing the progression of the first stages of melanoma.

Abstract
Two regions of northern Spain, Gipuzkoa, and Cantabria present high annual incidence of listeriosis (1.86 and 1.71 cases per 100,000 inhabitants, respectively). We report that the high annual incidences are a consequence of infection with highly virulent Listeria monocytogenes isolates linked to fatal outcomes in elderly patients with cancer. In addition, listeriosis patients with cancer present low IL-17A/IL-6 ratios and significantly reduced levels of anti-GAPDH1–22 antibodies, identified as two novel biomarkers of poor prognosis. Analysis of these biomarkers may aid in reducing the incidence of listeriosis. Moreover, GAPDH1–22-activated monocyte-derived dendritic cells of listeriosis patients with cancer seem useful tools to prepare clinical vaccines as they produce mainly Th1 cytokines.

Abstract
The prognostic factors and optimal therapy for invasive pulmonary aspergillosis (IPA) after kidney transplantation (KT) remain poorly studied. We included in this multinational retrospective study 112 recipients diagnosed with probable (75.0% of cases) or proven (25.0%) IPA between 2000 and 2013. The median interval from transplantation to diagnosis was 230 days. Cough, fever, and expectoration were the most common symptoms at presentation. Bilateral pulmonary involvement was observed in 63.6% of cases. Positivity rates for the galactomannan assay in serum and bronchoalveolar lavage samples were 61.3% and 57.1%, respectively. Aspergillus fumigatus was the most commonly identified species. Six- and 12-week survival rates were 68.8% and 60.7%, respectively, and 22.1% of survivors experienced graft loss. Occurrence of IPA within the first 6 months (hazard ratio [HR]: 2.29; p-value = 0.027) and bilateral involvement at diagnosis (HR: 3.00; p-value = 0.017) were independent predictors for 6-week all-cause mortality, whereas the initial use of a voriconazole-based regimen showed a protective effect (HR: 0.34; p-value = 0.007). The administration of antifungal combination therapy had no apparent impact on outcome. In conclusion, IPA entails a dismal prognosis among KT recipients. Maintaining a low clinical suspicion threshold is key to achieve a prompt diagnosis and to initiate voriconazole therapy.

Abstract
The use of endovascular catheters is a routine practice in secondary and tertiary care level hospitals. Short peripheral catheters have been found to be associated with the risk of nosocomial bacteremia resulting in morbidity and mortality. Staphyloccus aureus is mostly associated with peripheral catheter insertion. This Consensus Document has been elaborated by a panel of experts of the Spanish Society of Cardiovascular Infections in cooperation with experts from the Spanish Society of Internal Medicine, Spanish Society of Chemotherapy and Spanish Society of Thoracic-Cardiovascular Surgery and aims at define and establish the norm for management of short duration peripheral vascular catheters. The document addresses the indications for insertion, catheter maintenance and registry, diagnosis and treatment of infection, indications for removal and stresses on continuous education as a driver for quality. Implementation of this norm will allow uniformity in usage thus minimizing the risk of infection and its complications.

Abstract
Risk factors for invasive pulmonary aspergillosis (IPA) after kidney transplantation have been poorly explored. We performed a multinational case-control study that included 51 kidney transplant (KT) recipients diagnosed with early (first 180 posttransplant days) IPA at 19 institutions between 2000 and 2013. Control recipients were matched (1:1 ratio) by center and date of transplantation. Overall mortality among cases was 60.8%, and 25.0% of living recipients experienced graft loss. Pretransplant diagnosis of chronic pulmonary obstructive disease (COPD; odds ratio [OR]: 9.96; 95% confidence interval [CI]: 1.09-90.58; p = 0.041) and delayed graft function (OR: 3.40; 95% CI: 1.08-10.73; p = 0.037) were identified as independent risk factors for IPA among those variables already available in the immediate peritransplant period. The development of bloodstream infection (OR: 18.76; 95% CI: 1.04-339.37; p = 0.047) and acute graft rejection (OR: 40.73, 95% CI: 3.63-456.98; p = 0.003) within the 3 mo prior to the diagnosis of IPA acted as risk factors during the subsequent period. In conclusion, pretransplant COPD, impaired graft function and the occurrence of serious posttransplant infections may be useful to identify KT recipients at the highest risk of early IPA. Future studies should explore the potential benefit of antimold prophylaxis in this group.

Abstract
Bile duct is usually sterile, and the isolating of microorganisms (bacteriobilia) has been related to some factors, such as age, biliary drainage before pancreatic surgery or bile duct stones. Gramnegative strains remain the most frequent pathogens, especially Escherichia coli. Among grampositives Enterococcus spp should be mentioned. Currently, there is controversy about whether the presence of bacteriobilia has an impact on unfavorable outcome of biliary disease or surgical procedures or mortality rates, with complications such as surgical site infections or bacteremia. In high-risk patients, such as immunosuppressed or those underwent pancreaticoduodenectomy, bile duct cultures performed routinely, even if there are not clinical data of infection, could be necessary in order to start antibiotic treatment or to reduce its spectrum.

Abstract
OBJECTIVE At present there is a controversy regarding the impact of positive bile cultures on morbidity and mortality rates, and on the incidence of readmissions in patients with biliar disease. The aim of this study was to evaluate the role of bacteriobilia in postoperatory infections, mortality or readmissions in these patients. METHODS The information was obtained from all patients with bile cultures admitted to Hospital Universitario Marqués de Valdecilla (Santander, Spain) from January to December 2011. Clinical, epidemiological and microbiological data and laboratory findings were analyzed. The patients were followed for two years. RESULTS One hundred and fifty-two patients (65% men) were included. Mean age was 67 years (SD= 15 years). The most frequent diagnoses were acute cholecystitis (79%) and cholangitis (8%). Laparoscopic cholecystectomy was performed in 42% of patients, open cholecystectomy in 45% and percutaneous cholecystostomy in 8%. Bacteriobilia was present in 83 patients (55%). The most frecuent microorganisms isolated were Escherichia coli (31%), Enterococcus faecium (13%) and Klebsiella pneumoniae (13%). The initial antimicrobial agent was a carbapenem in 62 patients (44%) and piperacillin-tazobactam in 28 (18%). There were 39 postoperative infections (26%), 21 readmissions (14%) and 17 patients died during admission (11%). The presence of microorganisms in bile cultures was not a statistically significant predictor of neither complications nor readmissions. CONCLUSIONS Intra-operative bile cultures would allow guide early appropriate antibiotic treatment use in case of infection, or empiric antimicrobial therapy, however there was no correlation between bacteriobilia and postoperative infections, length of stay, mortality or readmissions.

Abstract
OBJECTIVE To evaluate the course of left-sided infective endocarditis (LsIE) in patients with liver cirrhosis (LC) analyzing its influence on mortality and the impact of surgery. METHODS Prospective cohort study, conducted from 1984 to 2013 in 26 Spanish hospitals. RESULTS A total of 3.136 patients with LsIE were enrolled and 308 had LC: 151 Child-Pugh A, 103 B, 34 C and 20 were excluded because of unknown stage. Mortality was significantly higher in the patients with LsIE and LC (42.5% vs. 28.4%; p < 0.01) and this condition was in general an independent worse factor for outcome (HR 1.51, 95% CI: 1.23-1.85; p < 0.001). However, patients in stage A had similar mortality to patients without cirrhosis (31.8% vs. 28.4% p = NS) and in this stage heart surgery had a protective effect (28% in operated patients vs. 60% in non-operated when it was indicated). Mortality was significantly higher in stages B (52.4%) and C (52.9%) and the prognosis was better for patients in stage B who underwent surgery immediately (mortality 50%) compared to those where surgery was delayed (58%) or not performed (74%). Only one patient in stage C underwent surgery. CONCLUSIONS Patients with liver cirrhosis and infective endocarditis have a poorer prognosis only in stages B and C. Early surgery must be performed in stages A and although in selected patients in stage B when indicated.

Abstract
Streptococcus pneumoniae is an infrequent cause of severe infectious endocarditis (IE). The aim of our study was to describe the epidemiology, clinical and microbiological characteristics, and outcome of a series of cases of S. pneumoniae IE diagnosed in Spain and in a series of cases published since 2000 in the medical literature. We prospectively collected all cases of IE diagnosed in a multicenter cohort of patients from 27 Spanish hospitals (n = 2539). We also performed a systematic review of the literature since 2000 and retrieved all cases with complete clinical data using a pre-established protocol. Predictors of mortality were identified using a logistic regression model. We collected 111 cases of pneumococcal IE: 24 patients from the Spanish cohort and 87 cases from the literature review. Median age was 51 years, and 23 patients (20.7%) were under 15 years. Men accounted for 64% of patients, and infection was community-acquired in 96.4% of cases. The most important underlying conditions were liver disease (27.9%) and immunosuppression (10.8%). A predisposing heart condition was present in only 18 patients (16.2%). Pneumococcal IE affected a native valve in 93.7% of patients. Left-sided endocarditis predominated (aortic valve 53.2% and mitral valve 40.5%). The microbiological diagnosis was obtained from blood cultures in 84.7% of cases. In the Spanish cohort, nonsusceptibility to penicillin was detected in 4.2%. The most common clinical manifestations included fever (71.2%), a new heart murmur (55%), pneumonia (45.9%), meningitis (40.5%), and Austrian syndrome (26.1%). Cardiac surgery was performed in 47.7% of patients. The in-hospital mortality rate was 20.7%. The multivariate analysis revealed the independent risk factors for mortality to be meningitis (OR, 4.3; 95% CI, 1.4-12.9; P < 0.01). Valve surgery was protective (OR, 0.1; 95% CI, 0.04-0.4; P < 0.01). Streptococcus pneumoniae IE is a community-acquired disease that mainly affects native aortic valves. Half of the cases in the present study had concomitant pneumonia, and a considerable number developed meningitis. Mortality was high, mainly in patients with central nervous system (CNS) involvement. Surgery was protective.

Abstract
OBJECTIVE To analyze the epidemiological and clinical characteristics and mortality of patients with cystic echinococcosis (CE) in northern Spain. PATIENTS AND METHODS A retrospective study of the medical records of patients diagnosed with CE and hospitalized from 1997 to 2011 in a University Hospital. RESULTS A total of 76 patients (44 men) were diagnosed with CE. The mean age was 57.8 years (SD: 19.1 years; range: 14.9-92.7). The yearly average incidence was 1.08 cases/100,000 inhabitants. The highest incidence was registered in patients aged 70-79 years (22.7% of all cases). Liver was the main organ involved (92.1%), followed by lung (6.6%) and peritoneum (1.3%). Fifty-five patients (72%) received treatment: 2 (3.6%) medical treatment with albendazole, 27 (49%) surgical treatment, 3 (5.4%) medical treatment combined with cyst drainage, and 23 (42%) combined medical and surgical treatment. Eight patients had a recurrence. Twenty-four (31.2%) patients died. No patient's death was attributed directly to hydatidosis, though mortality was significantly higher in the untreated vs. the treated patient group (57% vs. 22%, p=0.003). CONCLUSIONS Hydatidosis treatment and diagnostic approaches remain heterogeneous. The liver continues being the main organ affected. Mortality was higher in patients who did not receive treatment. However, this result might have been influenced by other factors, mainly age.

Abstract
BACKGROUND The most common cause of implant failure is aseptic loosening (AL), followed by prosthetic joint infection (PJI). This study evaluates the incidence of PJI among patients operated with suspected AL and whether the diagnosis of PJI was predictive of subsequent implant failure including re-infection, at 2 years of follow up. METHODS Patients undergoing revision hip or knee arthroplasty due to presumed AL from February 2009 to September 2011 were prospectively evaluated. A sonication fluid of prosthesis and tissue samples for microbiology and histopathology at the time of the surgery were collected. Implant failure include recurrent or persistent infection, reoperation for any reason or need for chronic antibiotic suppression. RESULTS Of 198 patients with pre-and intraoperative diagnosis of AL, 24 (12.1 %) had postoperative diagnosis of PJI. After a follow up of 31 months (IQR: 21 to 38 months), 9 (37.5 %) of 24 patients in the PJI group had implant failure compared to only 1 (1.1 %) in the 198 of AL group (p < 0.0001). Sensitivity of sonicate fluid culture (>20 CFU) and peri-prosthetic tissue culture were 87.5 % vs 66.7 %, respectively. Specificities were 100 % for both techniques (95 % CI, 97.9-100 %). A greater number of patients with PJI (79.1 %) had previous partial arthroplasty revisions than those patients in the AL group (56.9 %) (p = 0.04). In addition, 5 (55.5 %) patients with PJI and implant failure had more revision arthroplasties during the first year after the last implant placement than those patients with PJI without implant failure (1 patient; 6.7 %) (RR 3.8; 95 % CI 1.4-10.1; p = 0.015). On the other hand, 6 (25 %) patients finally diagnosed of PJI were initially diagnosed of AL in the first year after primary arthroplasty, whereas it was only 16 (9.2 %) patients in the group of true AL (RR 2.7; 95 % CI 1.2-6.1; p = 0.03). CONCLUSIONS More than one tenth of patients with suspected AL are misdiagnosed PJI. Positive histology and positive peri-implant tissue and sonicate fluid cultures are highly predictive of implant failure in patients with PJI. Patients with greater number of partial hip revisions for a presumed AL had more risk of PJI. Early loosening is more often caused by hidden PJI than late loosening.

Abstract
This cross-sectional study analyzes factors associated with the development of CMV-specific CD8+ response, measured by IFNg production after cytomegalovirus (CMV) peptide stimulation, in CMV-seropositive solid organ transplantation candidates. A total of 114 candidates were enrolled, of whom 22.8% (26/114) were nonreactive (IFNγ < 0.2 IU/mL). Multivariate logistic regression analysis showed that age, HLA alleles and organ to be transplanted were associated with developing CMV-specific CD8+ immunity (reactive; IFNγ ≥ 0.2 IU/mL). The probability of being reactive was higher in candidates over 50 than in those under 50 (OR 6.33, 95%CI 1.93-20.74). Candidates with HLA-A1 and/or HLA-A2 alleles had a higher probability of being reactive than those with non-HLA-A1/non-HLA-A2 alleles (OR 10.97, 95%CI 3.36-35.83). Renal candidates had a higher probability of being reactive than lung (adjusted OR 8.85, 95%CI 2.24-34.92) and liver candidates (OR 4.87, 95%CI 1.12-21.19). The AUC of this model was 0.84 (p < 0.001). Positive and negative predictive values were 84.8% and 76.9%, respectively. In renal candidates longer dialysis was associated with an increased frequency of reactive individuals (p = 0.040). Therefore, although the assessment of CMV-specific CD8+ response is recommended in all R+ candidates, it is essential in those with a lower probability of being reactive, such as non-renal candidates, candidates under 50 or those with non-HLA-A1/non-HLA-A2 alleles.

Abstract
INTRODUCTION Infections caused by resistant gram-positive cocci (GPC), especially to glycopeptides, are difficult to treat in solid organ transplant (SOT) recipients as a result of lower effectiveness and high rates of renal impairment. The aim of this study was to evaluate the use of daptomycin in this population. METHODS Over a 2-year period (March 2008-2010) in 9 Spanish centers, we enrolled all consecutive recipients who received daptomycin to treat GPC infection. The study included 43 patients, mainly liver and kidney transplant recipients. RESULTS The most frequent infections were catheter-related bacteremia caused by coagulase-negative staphylococci (23.2%), skin infection caused by Staphylococcus aureus (11.5%), and intra-abdominal abscess caused by Enterococcus faecium (20.9%). The daily daptomycin dose was 6 mg/kg in 32 patients (74.4%). On day 7 of daptomycin treatment, median estimated area under the curve was 1251 μg/mL/h. At the end of follow-up, analytical parameters were similar to the values at the start of therapy. No changes were observed in tacrolimus levels. No patient required discontinuation of daptomycin because of adverse effects. Clinical success at treatment completion was achieved in 37 (86%) patients. Three patients died while on treatment with daptomycin. CONCLUSION In summary, daptomycin was a safe and useful treatment for GPC infection in SOT recipients.

Abstract
The influenza pandemic that was declared by the World Health Organization in June 2009 created a new scenario for the use of influenza antivirals and vaccination. The new strain, influenza A(H1N1)pdm09, was resistant to amantadine and rimantadine, and the most frequently used antiviral was oseltamivir. Randomized studies were not performed comparing neuraminidase inhibitors with placebo. Nevertheless, experience from prospective and retrospective cohorts indicated that these drugs were useful for improving the prognosis of patients admitted to hospitals, especially for those with more severe disease. Treatment with oseltamivir was associated with a reduction in days of fever, length of hospital stay, use of mechanical ventilation and mortality. Treatment was more effective if it was begun within the first 48 h after the onset of symptoms, but it was also useful if begun later. A safe and effective vaccine to prevent disease from this new influenza strain was available in developed countries soon after the pandemic began; thus, the rate of adverse effects was comparable to that of seasonal influenza vaccines. The main barrier to its use was the concern of target populations about its necessity and safety. Therefore, the challenges for future pandemics will be to increase the population coverage of the vaccine in developed countries and to make it affordable for developing countries.

Abstract
Toll-like receptors (TLRs) are key sensors of mycobacterial infections and play a crucial role in the initiation and coordination of the antimycobacterial innate immune response. T1805G, a functional TLR1 single nucleotide polymorphism (SNP), has been associated with susceptibility to pulmonary tuberculosis (PTB), but contradictory results among different populations have been reported. Our objective was to study this SNP in a genetically homogeneous population to evaluate its role in conferring susceptibility or resistance to PTB. In our population, the 1805G allele and the GG genotype (OR 2.04, 95%CI 1.26-3.31) influence susceptibility to PTB, in contrast with data observed in other populations.

Abstract
BACKGROUND Staphylococcus aureus bacteremia (SAB) is associated with significant morbidity and mortality. Several aspects of clinical management have been shown to have significant impact on prognosis. The objective of the study was to identify evidence-based quality-of-care indicators (QCIs) for the management of SAB, and to evaluate the impact of a QCI-based bundle on the management and prognosis of SAB. METHODS A systematic review of the literature to identify QCIs in the management of SAB was performed. Then, the impact of a bundle including selected QCIs was evaluated in a quasi-experimental study in 12 tertiary Spanish hospitals. The main and secondary outcome variables were adherence to QCIs and mortality. Specific structured individualized written recommendations on 6 selected evidence-based QCIs for the management of SAB were provided. RESULTS A total of 287 and 221 patients were included in the preintervention and intervention periods, respectively. After controlling for potential confounders, the intervention was independently associated with improved adherence to follow-up blood cultures (odds ratio [OR], 2.83; 95% confidence interval [CI], 1.78-4.49), early source control (OR, 4.56; 95% CI, 2.12-9.79), early intravenous cloxacillin for methicillin-susceptible isolates (OR, 1.79; 95% CI, 1.15-2.78), and appropriate duration of therapy (OR, 2.13; 95% CI, 1.24-3.64). The intervention was independently associated with a decrease in 14-day and 30-day mortality (OR, 0.47; 95% CI, .26-.85 and OR, 0.56; 95% CI, .34-.93, respectively). CONCLUSIONS A bundle orientated to improving adherence to evidence-based QCIs improved the management of patients with SAB and was associated with reduced mortality.

Abstract
Although peripheral facial palsy is the most common cranial neuropathy in HIV-infected patients, no series have been reported recently in the literature. In this study we reviewed the clinical records of HIV-infected patients with a diagnosis of peripheral facial palsy between 2000 and 2011 attending the Hospital Marqués de Valdecilla (Infectious Diseases Unit), a 900-bed university hospital in northern Spain. We identified eight patients (4 men, 4 women): median CD4 count and viral load were 232 cells per μL and 130,000 RNA copies per mL, respectively. Most of them presented co-morbidities, including hepatitis C virus in 75%, hepatitis B virus in 15% and tuberculosis in 15%. Aetiologies of palsy were varied: idiopathic Bell's palsy predominated at early stages of the disease, whereas secondary causes, such as lymphoma and infections were frequently the cause of paralysis in advanced HIV/AIDS. At early stages of HIV infection, facial palsy is similar, both in aetiology and prognosis, to cases in the general population. However, in advanced stages the palsy is frequently secondary to underlying complications. Clinicians should be aware of these differences to tailor the diagnostic work-up.

Abstract
BACKGROUND The incidence and clinical significance of pulmonary residual thrombosis 6 months after an acute pulmonary embolism (PE) are still not well-known. PURPOSE To evaluate the association between residual vascular obstruction and the risk of venous thromboembolism (VTE) recurrence or death. MATERIAL AND METHODS Computed tomography pulmonary angiography (CTPA) was repeated in 97 consecutive patients 6 months after an acute episode of hemodynamically stable pulmonary embolism. We assessed the long-term consequences of residual thrombosis on vital status and incidence of recurrent VTE. RESULTS Six patients were lost for follow-up. The remaining 91 patients were classified according to the presence (Group 1: 18 cases) or absence (Group 2: 73 cases) of residual pulmonary vascular obstruction. After a mean ± SD of 2.91 ± 0.99 years, there were eight (8.8%) deaths and 11 (12.1%) VTE recurrences. Groups 1 and 2 did not differ in the incidence of death or VTE recurrence. CONCLUSION Persistent pulmonary vascular obstruction on 6-month CTPA did not predict long-term adverse outcome events.

Abstract
The purpose of this investigation was to assess the prevalence of upper urinary tract involvement in patients with candiduria by means of (111)indium-oxine-labeled leukocyte scintigraphy. An observational cohort study of patients with confirmed candiduria was conducted in an acute-care teaching hospital in Spain from March 2006 through February 2009. An (111)In-labeled leukocyte scan was performed in order to assess the upper urinary tract involvement. A series of non-matched patients without candiduria nor bacteriuria undergoing scintigraphy to exclude infections in other sites than the urinary tract was also studied. Demographics, baseline illness, and clinical data were recorded. Candiduria was detected in 428 patients, and scintigraphy was performed in 35 of these patients. Twenty-nine patients without candiduria nor bacteriuria were also studied. Positive renal scintigraphy was documented in 24 (68%) patients with confirmed candiduria and in 3 (10%) patients without candiduria (p < 0.005). Renal uptake was not associated with a higher mortality nor with re-admissions. Subclinical pyelonephritis could be more frequent in patients with candiduria than it has been previously considered.

Abstract
BACKGROUND The outcome of patients with influenza A 2009 (H1N1)v virus infection taking into account hospital type has not been elucidated. OBJECTIVES To compare risk factors, clinical features and outcome of patients admitted to 3 public hospitals with different levels of health-care. METHODS Prospective study of all non-pregnant adult patients admitted to 3 hospitals with pandemic H1N1 infection, from June 1 to December 31 and followed up until 1 month after discharge. RESULTS During the study period, 111 patients with a mean age of 49 years (15-89) were hospitalized: 52 in hospital 1 (900-bed tertiary-teaching-hospital), 33 in hospital 2 (315-beds secondary-hospital) and 26 in hospital 3 (150-beds primary-care-hospital).Overall 80% of patients had at least 1 comorbid condition with no differences between hospitals. Symptoms or signs on admission were similar except for cough (P=0.01) more frequent in patients in hospital 1 and dyspnea (P=0.05), myalgia, arthralgia (P=0.04) and hypoxemia (P=0.009) present in more patients in hospital 2. In-hospital mortality rates were not statistically different between hospitals. In the stepwise analysis, independent predictors of mortality were pneumonia on admission (adjusted OR=8.68, 95%CI 1.0-82.43) and cardiac complications during hospitalization (adjusted OR=13.2, 95%CI 1.67-103.98). CONCLUSIONS Mortality of patients with pandemic H1N1 infection was influenced by patients underlying conditions, severity of disease (pneumonia) on admission and complications during hospitalization. Hospital-characteristics do not appear to have influenced severe outcome.

Abstract
Solid organ transplant recipients (SOTR) are at risk of serious influenza-related complications. The impact of respiratory co-infection in SOTR with 2009 pandemic influenza A(H1N1) is unknown. A multicentre prospective study of consecutive cases of pandemic influenza A(H1N1) in SOTR was carried out to assess the clinical characteristics and outcome and the risk factors for co-infection. Overall, 51 patients were included. Median time from transplant was 3.7 years, 5.9% of the cases occurred perioperatively and 7.8% were hospital-acquired. Pneumonia was diagnosed in 15 (29.4%) patients. Ten cases were severe (19.6%): 13.7% were admitted to intensive care units, 5.9% suffered septic shock, 5.9% developed acute graft rejection and 7.8% died. Co-infection was detected in 15 patients (29.4%): eight viral, six bacterial and one fungal. Viral co-infection did not affect the outcome. Patients with non-viral co-infection had a worse outcome: longer hospital stay (26.2 ± 20.7 vs. 5.5 ± 10.2) and higher rate of severe diseases (85.7% vs. 2.3%) and mortality (42.8% vs. 2.3%). Independent risk factors for non-viral co-infection were: diabetes mellitus and septic shock. Other factors associated with severe influenza were: delayed antiviral therapy, diabetes mellitus, time since transplantation <90 days and pneumonia. In conclusion, pandemic influenza A can cause significant direct and indirect effects in SOTR, especially in the early post-transplant period, and should be treated early. Clinicians should be aware of the possibility of non-viral co-infection, mainly in diabetic patients and severe cases. An effort should be made to prevent influenza with immunization of the patient and the environment.
